Change some char in char array

[Brkic]

Hi everybady,

i have problem with some code

char ONE[1];
char MENU[][maxItemSize] ={"Date","Time","Alarm","Format","Zone","Daylight","BACK"};
.
..
...

strcpy(ONE,"Proba");

I want change MENU[1] with ONE //MENU[1]=Time and i want MENU[1]=Proba

///

when ONE is string i will use ONE.toCharArray(MENU[2], ONE.length()+1); and everything is work but with ONE=char i dont know.

Somebody can help me, thanks.

Code: [Select]

char ONE[1];
How many characters can this array hold ?

Code: [Select]

strcpy(ONE,"Proba");
How many characters are you copying to it ?

[Brkic]

ONE have One character

strcpy(ONE,"P");  // this is only example "P" or "Proba"

[Delta_G]

ONE have One character

strcpy(ONE,"P");  // this is only example "P" or "Proba"

Even "P" is actually 2 characters.  It's the 'P' and also the null terminator '\0'

You need ONE to have the same number of characters as the second dimension of MENU.  So use MaxItemSize there.

OK, I will change that

char ONE[2];
char MENU[][maxItemSize] ={"Date","Time","Alarm","Format","Zone","Daylight","BACK"};
.
..
...

strcpy(ONE,"P");

I want change MENU[1] with ONE //MENU[1]=Time and i want MENU[1]=P

[Delta_G]

I want change MENU[1] with ONE //MENU[1]=Time and i want MENU[1]=P

I don't understand what you mean by this.

Maybe:

Code: [Select]


strcpy(MENU[1], "P");


or

Code: [Select]


strcpy(MENU[1], ONE);


[Brkic]

This is a code when ONE is string

char MENU[][maxItemSize] ={"Date","Time","Alarm","Format","Zone","Daylight","BACK"};
String ONE;

void niz()
  {
    ONE="Proba";
    ONE.toCharArray(menu[1], amp.length()+1);
  }

and that code is work OK,

now ONE is char,how to replace value in a MENU

char ONE[6];

Thanks it worked !! :-)

Code: [Select]


strcpy(MENU[1], ONE);


[Delta_G]

Thanks it worked !! :-)

Code: [Select]


strcpy(MENU[1], ONE);


Yeah, it's the same as this one that you were already using:

Code: [Select]

strcpy(ONE,"P");


I guess that's why it was confusing.  You seemed to already understand the answer.
